Platform data

Overview

Detailed view

Based on Cajanuma Thies station 1998 - Feb. 2013 

Gap filled and quality check Feb 2013 until Dec 2017 UTPL station Finca Jipiro Alto relatively close by.
Remaining gaps are filled with various stations, mostly Thies station "El Tiro"

Methods: Regression from overlapping periods

Restriction for rainfall since 2013 ! No dry days at the station, otherwise too low rainfall totals 
(thus, do not use this parameter for climate change analyses regarding changes of dry days!)

This dataset contains fruit phenology data from 37 fleshy-fruited species at three different altitudes (1000, 2000, 3000 masl) over 10 months (2019 & 2020).

Corrected plots from Bombuscaro, ECSF, Cajanuma, Zamora and Laipuna region as shape files.

Ongoing data collected from the Cajanuma tower station at 2888 masl.

Raw data, initial visual control only. Use data with great care, errors might be included.

Abundance of ant species were collected during the wet and the dry season 2014 on the core plots and intermediate elevation levels (1000, 1500, 2000, 2500, 3000) on disturbed and undisturbed forest plots.

The AMF sequences were divided into OTUs based on 99% sequence similarity. It revealed that AMF species compositions at 1000 and 2000 masl differ from 3000 and 4000 masl. Lower elevations (1000 and 2000 masl) were dominated by members of Glomeraceae, whereas Acaulosporaceae were more abundant in higher elevations (3000 and 4000 masl).

Monthly measurement of soil temperature and soil gas fluxes (CO2, N2O) in the NUMEX plots in Bombuscaro, ECSF und Cajanuma

Monthly measurements of gas fluxes were performed using static vented chambers.
Soil temperature was taken simultaneously with gas measurements.

The dataset includes chemical properties of the organic layer and mineral soil on forest and pastures core plots in Cajanuma during sampling campaigns in 2018 and 2019. Three soil profiles were established on each core plot. Respresentative samples were taken from each horizon, dried and transported to Germany for laboratory analyses. Available nitrogen (NH4-N and NO3-N) was immediately extracted in the laboratory of the ECSF with 1 M KCl. The extracts were frozen and sent to Germany for laboratory analyses by continuous flow analysis. Following properties were measured in the < 2mm soil fraction: available P after extraction by the Olsen method with 0.5 M NaHCO3 and measurement by continuous flow analysis, total element concentrations Al, Fe, Mn, Zn, C, N, S, P, K, Na, Mg, Ca after microwave pressure digestion with HNO3, H2O2 and HF and measurement by by ICP-OES or ICP-MS, effective cation exchange capacity and exchangeable cations Ca, Na, Mg, K, Al, Fe, Mn after unbuffered extraction with 1M NH4NO3 and measurement by ICP-OES.

Herbivory estimated as leaf area loss [cm^2] and [%] and leaf traits were generated from sun-exposed leaves of 380 tree canopies belonging to 51 tree species (7 +/- 1 tree individual per species) located within the nine 1 ha forest core plots at 1000 m (Bombuscaro), 2000 m (San Francisco), and 3000 m (Cajanuma) in the Podocarpus Nationalpark and the Reserva Biológica San Francisco in southern Ecuador between February and March in 2019.
To estimate herbivory, 20 +/- 5 leaves per tree were scanned and analyzed with the software WinFOLIA. Leaf traits were either measured conventionally with morphometrical and chemical measurement techniques or spectrally with an OceanOptics spectrometer HDX to identify the reflectance wavebands of certain molecular foliar structures.

This dataset is a joined work of the RESPECT subprojects A1 (provided spectrally estimated leaf traits), B1 (provided leaf traits derived from conventional measurement techniques), and B4 (provided herbivory data).

Tree species inventories of the three Cajanuma Respect plots.
All individual stems are listed with their identity and dbh (first inventory in 2018).
